1 Claim. (01. 104-41) My invention relates to improvements inturntable's. 1 l The object of my invention is to provide a turn tablehaving duplex tracks thereonalter- -'5 nately engaged atea-ch rotationof the table.

A further object of my invention is to provide a'turn table that isautomatically turned by the automobile, and astopping means for thecorrect position of the same that is automatic 10 likewise. I a I Astill further object of my invention is to provide a turn table having arevolving means to turn the same in one continuous direction.

A still further object of my invention is to 5 provide a turn table forautomobiles or the like having the carrying and rotating means thereforpositioned in a pit and a disc covering the same to protect it againstthe action of the ele- I ments and to serve as a safeguard againstaccidents to pedestrians.

A still further object of my invention is to provide a turn table thatis economical in the construction and installation thereof.

I These and other objects will hereinafter be more fully explained,reference being had to the accompanying drawings forming a part of thisspecification, and in which like characters will apply to like parts inthe different views.

Referring to the drawings:

Fig. 1 is a plan view of the turn table, parts being removed forconvenience of illustration.

Fig. 2 is a sectional view taken on line 2--2 in Fig. 1, looking in thedirection of the arrows, and p showing the turn table with an automobileplaced thereon to illustrate the purpose of certain elements.

Fig. 3 is an inverted plan view of the turn table. Fig. 4 is an enlargeddetail view of the ratchet controlling means for the rollers.

: My invention herein disclosed consists of a pair of tracks 1 and asecond pair of tracks 2 parallel therewith and in close proximitythereto, the direction of travel on each pair being in oppositedirections as indicated by arrows.

Centrally, arranged and transversely positioned relative to the tracksis a plate 3 secured thereto and being apertured to rotatably engage onthe center post 4, the said post extending downward and being rigidlysecured in the bottom of the pit 5.

Each end of the adjacent tracks is carried by a roller 6, each rollerbeing trunnioned on a U- shaped bearing that is secured to itsrespective 5 end of the track and is tangentially positioned withrespect to the line of travel-as the table is turned.- 1 ul Secured tothe under side 'ofthe track element is a disc 9 which serves as. closingmeans'for the topof the pit. The peripheral edge'of the disc floats in arabbet formed around'the top of the pit as at 10, the outer portion ofwhich r'abbet slopes downward and outward to fun-ctionr as a drain forwater flowing from the disc. The said rabbet has tile laterals outwardlyextending therefrom"-functioning as a drain therefor, but

are not shown in -the draw'ings.

The track members 1 and 2 that are adjacent are integrally joined andhave a flange 11 on the outer sides of each and a flange 12intermediartely positioned and functioning as a guide for the wheels ofa vehicle as they pass along the track.

When the table is positioned before the door of a private garage, thefunction will be as follows:

The vehicle will enter tracks 1 to a point as shown by the position ofan automobile in Fig. 2, at which point the front wheel will impose itsweight upon plate 13 that is hingedly connected to the track at one endand which is slanted upward normally by a spring tensioning means laterdescribed, and when pressed downward as above stated a second plate 14positioned near the other end of the track will be vertically positionedthru the medium of a connecting rod consisting of a shaft 15telescopically engaging in a sleeve 16 and urged in one direction by aspring 17. By this means plate 14 may be rocked downward when plate 13is depressed, but may be anchored vertically by a pin 15 engaging in 80an elongated slot 16'. The said slot will permit the travel of the pinfor the downward movement of plate 14 against the resistance ofcompression spring 1'7 when plate 13 is compressed to snug engagement onthe track. To normally position the said plate 14 on a plane with thetrack, I have arranged a spring 18, one end of which is secured to thetrack, and the other end connected to the sleeve 16 as retracting meansfor the sleeve and shaft.

An automobile on the track is free to move onward until the front wheelis positioned on plate 13 at which instant the plate 14 is erectedvertically as shown in Fig. 2, functioning as a stop against which oneof the rear wheels will 1.0

engage, and being thus stopped the other rear wheel will be positionedon roller 19 that is frictionally rotated thereby, and to avoid contactof the said wheel and the track during rotation end of the track and istangentially positioned "1:10

rollers 20, one of which is positioned on each side of roller 19 and inclose proximity thereto. Rotation of roller 19 causes rotation of thetable thru the medium of a chain 21 engaging on a sprocket wheel 22 thatis secured to the shaft of the said roller 19, and a second sprocketwheel 23 that is placed on the shaft of a bevel gear 24, the said gearand sprocket being trunnioned on a bearing 25 that is secured to theunder side of plate 3. The said gear is in mesh with an annular gear 26that is concentrically secured v to the bottom of the pit.

It is now readily seen how the turn table-Eis rotated around its centerbearing thru power transmitted by the automobile which may be" backedinto the garage and driven out without interference from the plates androllers.

In Fig. 4 is shown a pawl 27 rockably arranged to engage with a toothedwheel 28, by which means the rotation of roller 19 is permitted in onedirection, and. preventedin the other. The

approach on the turn table is at all timesover the right hand pair oftracks, and whenthe table is turned the car is backed into the garage,and to. remove the car it will be guided over the other pair of trackswithout energizing the turning means of. the table.

While I have shown and described, a turn -.table.with its operatingmechanism housed within a pit, I do not wish to be restricted to thisconstruction alone, as the mechanism disclosed may be elevated, andapproached by a ramp. By

-' Patent is In a turntable of the class described comprising two pairsof tracks in parallelism, and a center post; rollersto carry the trackswhen turned on the center post, a plate hingedly mounted near one endofone-track-of each pair of tracks, a stop hinged near the other end ofeach of the same tracks, means connecting each plate With .its;corresponding stop member so that weight imposed on a plate will raisethe stop member to engage an automobile wheel; the corresponding trackhaving a series of rollers arranged lone gitudinally thereof anddirectly opposite to the;

stop member: of the associated track; one of said rollers being adaptedto be rotatedby an automobile wheel and to transmit, through the mediumof a series of gears, power from said wheel to rotate the turn table.
